Comparative Study Controlled Clinical TrialThe Comparison between Minimally Invasive Coronary Bypass Grafting Surgery and Conventional Bypass Grafting Surgery in Proximal LAD Lesion.
Minimally invasive bypass grafting surgery has entered the clincal routine in several centers around the world, with an increasing popularity in the last decade. In our study, we aimed to make a comparison between minimally invasive coronary artery bypass grafting surgery and conventional bypass grafting surgery in isolated proximal left anterior descending artery (LAD) lesions. ⋯ In isolated proximal LAD stenosis, robotic assisted minimally invasive coronary artery bypass grafting surgery requires less blood products, is associated with shorter ICU and hospital stay, and lesser pain in the early postoperative period in contrast to conventional surgery. The result of our studies, which showed similarities to the past studies, lead us to recognize the importance of minimally invasive interventions and the need to perform them more frequently in the future.

Is long-term warfarin therapy necessary in Chinese patients with atrial fibrillation after bioprosthetic mitral valve replacement and left atrial appendage obliteration?
Long-term warfarin therapy has been used to decrease thromboembolic events in patients with atrial fibrillation (AF) following bioprosthetic mitral valve replacement (BMVR) and left atrial appendage obliteration (LAAO). A retrospective study was conducted to investigate the efficacy of long-term warfarin or aspirin therapy in patients with AF after BMVR and LAAO. ⋯ At the current time in China, long-term warfarin or aspirin therapy may have no significantly different impact on long-term prognosis after 3 months anticoagulation with warfarin in patients with AF undergoing BMVR and LAAO.

Case ReportsInsertion of the Avalon cannula for venovenous extracorporeal membrane oxygenation in a patient with an implanted ASD occlusion device.
Use of the Avalon Elite bicaval dual lumen catheter (Maquet Cardiopulmonary AG, Rastatt, Germany) can be effective in patients requiring venovenous extracorporeal membrane oxygenation (VV-ECMO) for adult respiratory distress syndrome (ARDS). Proper placement of the cannula is important in providing adequate therapy and avoiding life-threatening complications. We report a case of successful cannulation in a patient with an implanted atrial septal defect (ASD) occlusion device who developed severe refractory ARDS.

Controlled Clinical TrialEvaluation of myocardial contractility determination with tissue tracking echocardiography after levosimendan infusion in patients with poor left ventricular function and hemodynamics.
The aim of this study was to assess the effect of conventional inotropic drugs compared to levosimendan using tissue tracking echocardiography in the early postoperative period for patients with low ejection fraction undergoing coronary artery bypass graft (CABG) surgery. ⋯ Levosimendan enhances functional myocardial tissue mass and ensures positive hemodynamic effect in the early postoperative period in patients with low ejection fraction undergoing elective CABG.

Relationship between nadir hematocrit during cardiopulmonary bypass and postoperative hyperglycemia in nondiabetic patients.
Hyperglycemia is common after cardiac surgery in both diabetic and nondiabetic patients and is associated with increased morbidity and mortality. Association between nadir hematocrit levels on cardiopulmonary bypass (CPB) and postoperative hyperglycemia is not clear. This study was carried out to determine the relationship between nadir hematocrit during CPB and postoperative hyperglycemia in nondiabetic patients. ⋯ Nadir hematocrit levels on CPB less than 20% and allogenic blood transfusions were independently associated with postoperative hyperglycemia in nondiabetic patients. Patients with a nadir hematocrit levels less than 20 % during CPB should be closely monitored for hyperglycemia in the perioperative period.
